Description

Technical Field

[0001] The present invention relates to the technical field of grounding wire devices, and in particular to an easy-to-operate short-circuit grounding wire device. Background Art

[0002] The short-circuit grounding device is an important safety device in the power system. It is used to short-circuit and ground the conductors of power-off equipment during maintenance or other situations to ensure the safety of personnel. The device can quickly and effectively conduct fault current to the ground. To prevent the equipment from being energized and avoid the risk of electric shock to personnel, the device usually consists of a grounding wire, a grounding clamp and an insulated operating rod. Regular inspection and maintenance are required to ensure its reliability.

[0003] The grounding wire is made of thicker soft copper wire, so it is relatively heavy. When the operator hangs the grounding wire, he needs to use an insulated operating rod to lift the end with the copper wire off the ground and make it fully upright. During this process, the center of gravity of the entire operating rod is relatively high, while the operator's point of force is relatively low. It is difficult to control the entire grounding device steadily by relying solely on hand strength. After all, the insulated operating rod is light, while the wire is heavy. If you are not careful, the insulated operating rod will fall, which may cause a series of safety accidents: once the insulated operating rod falls, it is difficult to control it, which is very likely to cause harm to people around it. In addition, during the tilting process, the center of gravity of the entire device is biased upward, and the operator's point of force is low. This uneven force may cause the insulated operating rod to deform and bend, and even risk breaking. Summary of the Invention

[0004] Based on this, it is necessary to provide an easy-to-operate short-circuit grounding wire device to address the problem that the current grounding wire device has a center of gravity that is biased upward, which poses a safety hazard to operators during operation.

[0005] The above purpose is achieved through the following technical solutions:

[0006] An easy-to-operate short-circuit grounding wire device comprising:

[0007] An insulating operating rod, one end of which is connected to a grounding cable, and the other end of which is provided with a terminal;

[0008] A clamping assembly, the clamping assembly being used to connect the terminal head to the cable to be repaired;

[0009] An auxiliary rod, one end of which is provided with a wire hanging hook for connecting the cable to be repaired, and the other end of the auxiliary rod is hinged to the middle position of the insulating operating rod;

[0010] A through hole is provided in the middle of the wire hanging hook, and a wiring head at one end of the insulating operating rod is adapted to the through hole.

[0011] Furthermore, a rotation groove is provided on one end of the auxiliary rod hinged to the insulating operating rod, and a hinge shaft is fixedly provided at the middle position of the insulating operating rod. The axis of the hinge shaft is perpendicular to the axis of the insulating rod, and the hinge shaft is rotatably connected in the rotation groove.

[0012] Furthermore, the locking assembly includes a terminal post, a sliding rod and an elastic member. The sliding rod is axially slidably arranged inside the insulating operating rod. The terminal head has a cavity, which can accommodate the cable to be repaired. One end of the sliding rod extends into the cavity. The terminal post is fixedly connected to the end of the sliding rod extending into the cavity. The elastic member is sleeved on the outer periphery of the sliding rod to push the terminal post to abut against the inner wall of the top of the terminal head.

[0013] Furthermore, the locking assembly also includes an adjustment plate and a holding handle, and the adjustment plate is provided with a first connecting shaft and a second connecting shaft parallel to each other, the first connecting shaft is fixedly connected to the outer periphery of the insulating operating rod, and the axis of the first connecting shaft is perpendicular to the axis of the insulating operating rod, the second connecting shaft is fixedly connected to the outer periphery of the sliding rod, and the axis of the second connecting shaft is perpendicular to the axis of the sliding rod, and the holding handle is fixedly connected to one side of the adjustment plate.

[0014] Furthermore, the elastic member is a compression spring.

[0015] Furthermore, a guiding slope is provided on the inner wall of the top of the wiring head, and the guiding slope can contact the cable to be repaired. A limiting groove is provided on the inner wall of the top of the wiring head, and the limiting groove is transitionally connected to the guiding slope in an arc.

[0016] Furthermore, a hinged pile is provided on the wiring head, and the end of the grounding cable is hinged to the hinged pile.

[0017] Furthermore, the wire hanging hook at one end of the auxiliary rod is in a duckbill shape.

[0018] Furthermore, a connecting hook is provided on one end of the insulating operating rod connected to the grounding cable, and a fixing clip is provided at the middle position of the insulating operating rod, and the fixing clip and the connecting hook are on the same vertical line.

[0019] Furthermore, a rectangular through groove is provided on the auxiliary rod, the rectangular through groove is connected to the through hole, and the rectangular groove is adapted to the insulating operating rod.

[0020] The beneficial effects of the present invention are:

[0021] The present invention hinges an auxiliary rod at the middle of the insulating operating rod, utilizes the gravity of the suspended grounding cable to rotate the insulating operating rod around the hinge center, and points the heavier end downward, thereby lowering the center of gravity during operation, avoiding that the operator can lift the heavy object only by hand strength, reducing the risk of the insulating operating rod tipping over, ensuring the safety of surrounding personnel, and preventing the insulating operating rod from deforming, bending or breaking due to uneven force. The operator does not need to lift the operating rod vertically with effort, but only needs to hang the auxiliary rod on the cable to be repaired, and automatically adjust the position of the terminal head with the help of gravity, which simplifies the connection process of the grounding cable, makes the operation more convenient and quick, reduces the working time, and improves work efficiency.

[0022] The present invention controls the opening and closing of the terminal post through the cooperation of the terminal post, sliding rod and compression spring in the locking assembly, as well as the adjustment plate and gripping handle, so as to facilitate the clamping of the cable to be inspected. The guiding slope and limit groove on the top of the terminal head facilitate the entry of the cable and stabilize its position in the terminal head, reduce the influence of external force disturbance, and provide a stable foundation for subsequent operations.

[0023] The present invention hinges the connection head with the grounding cable, and the grounding cable is connected to the grounding assembly via a fixing clamp and a connecting hook to form a stable connection system. The fixing clamp prevents the grounding cable from shaking in the middle, and the connecting hook facilitates the insertion and positioning of the cable. The double protection enhances the connection reliability and reduces the safety hazards caused by the loosening of the grounding cable.

[0024] The present invention provides a duckbill-shaped wire hanging hook with a wide and outward-expanding opening, which is convenient for quick alignment and hanging on the cable to be repaired. The anti-slip texture or rubber pad on the inside can increase the friction, ensuring that the wire hanging hook is not easy to slip in complex environments, providing stable support for maintenance operations.

[0041] Refer to the following Figures 1-8 The present invention provides a short-circuit grounding wire device that is easy to operate.

[0042] The grounding cable 400 is connected to the grounding cable 400 on the insulating operating rod 100.

[0043] Therefore, in order to solve the above problems, the present invention is to hinge an auxiliary rod 300 at the middle position of the insulating operating rod 100, and the auxiliary rod 300 can rotate around the hinge position. A wire hanging hook 310 is provided on one end of the auxiliary rod 300, and the wire hanging hook 310 is used to hang on the cable that needs to be repaired. The other end of the auxiliary rod 300 is hinged to the middle position of the insulating operating rod 100, and a through hole 330 is opened in the middle position of the wire hanging hook 310. The size of the through hole 330 is adapted to the size of the terminal head 110, so that the terminal head 110 can pass through the through hole 330. When the operator connects the grounding cable 400, as shown in FIG. Figure 8 As shown, one end of the grounding cable 400 is connected to one end of the insulating operating rod 100, and the grounding cable 400 is connected to the terminal 110. Due to the heavy weight of the grounding cable 400 and the terminal 110, the insulating operating rod 100 is hinged so that the terminal 110 of the insulating operating rod 100 is at the bottom. Figure 1 As shown, when the operator hangs one end of the auxiliary rod 300 with the hanging hook 310 on the maintenance cable, since the grounding cable 400 is long and in a suspended state, its weight is greater than the end of the insulating operating rod 100 with the terminal head 110, so that the insulating operating rod 100 rotates around the hinge position to exchange the position of the terminal head 110, so that the terminal head 110 is located at the top, and the terminal head 110 is close to the cable that needs to be inspected. The locking assembly on the terminal head 110 connects the cable that needs to be inspected to the terminal head 110, thereby completing the grounding operation of the cable that needs to be inspected, and subsequent maintenance operations can be performed.

[0044] It can be understood that by setting the auxiliary rod 300 and hingedly setting the middle position of the auxiliary rod 300 and the insulating operating rod 100, the heavier end of the insulating operating rod 100 is facing downward. When the operator operates, the center of gravity of the insulating operating rod 100 is biased downward, and the operation is stable. When the auxiliary rod 300 is hung on the cable to be inspected, the gravity of the suspended grounding cable 400 is used to rotate the insulating operating rod 100 around the hinge center, thereby rotating the heavier end of the insulating operating rod 100 upward, and then connecting the terminal 110 on the insulating operating rod 100 to the cable to be inspected. The operator no longer needs to lift the operating rod vertically, but only needs to hang the auxiliary rod 300 on the cable to be inspected. It is convenient and quick, and can also avoid accidents.

[0045] Specifically, such as Figure 3 and Figure 6 As shown, a rotation groove 320 is provided on one end at which the auxiliary rod 300 and the insulating operating rod 100 are hinged, and a hinge shaft 350 is fixedly provided at the middle position of the insulating operating rod 100. The axis of the hinge shaft 350 is perpendicular to the axis of the insulating operating rod 100, and both ends of the hinge shaft 350 are rotatably connected in the rotation groove 320, so that the insulating operating rod 100 can rotate with the hinge shaft 350 as the rotation center.

[0046] It should be noted that, in this embodiment, the rotation groove 320 is open, that is, the rotation groove 320 has an opening, and the hinge shaft 350 can enter the rotation groove 320 through the opening, and can also be separated from the rotation groove 320 through the opening. The setting of the open rotation groove 320 facilitates the installation and disassembly of the insulating operating rod 100.

[0047] More specifically, the engaging assembly in this embodiment includes a terminal post 160, a slide rod 150 and an elastic member 170. The slide rod 150 is axially slidably arranged inside the insulating operating rod 100, and one end of the slide rod 150 extends out of the insulating operating rod 100. Figure 2 and Figure 5As shown, the terminal head 110 has a cavity inside, which can accommodate the cable to be repaired, and one end of the cavity has an opening, through which the cable to be repaired can enter the cavity, and one end of the slide rod 150 extends into the terminal head 110, and the terminal post 160 is fixedly set on the end of the slide rod 150 extending into the terminal head 110. The terminal post 160 is conical in shape, with the large end facing the inner wall of the top of the terminal head 110 and the small end fixedly connected to the slide rod 150. The elastic member 170 is sleeved on the outer periphery of the insulating operating rod 100 extending from the slide rod 150. The elastic member 170 in this embodiment is a compression spring, and one end of the elastic member 170 is fixed to the terminal post 1 The small end of the terminal post 160 and the other end of the elastic member 170 are fixed to the inner wall at the bottom of the terminal head 110. When it is not in use, the elastic member 170 presses the terminal post 160 against the inner wall at the top of the terminal head 110. When the sliding rod 150 moves downward relative to the insulating operating rod 100, the sliding rod 150 pulls the terminal post 160 to squeeze the elastic member 170. At this time, the top of the terminal post 160 is separated from the inner wall at the top of the terminal head 110. The cable to be repaired can be accommodated between the top of the terminal post 160 and the inner wall at the top of the terminal head 110. When the elastic member 170 is reset, it pushes the terminal post 160 to press the repair cable so that the repair cable is pressed against the inside of the terminal head 110.

[0048] It should be noted that, in order to realize the downward movement of the sliding rod 150 relative to the insulating operating rod 100, the engaging assembly in this embodiment further includes an adjusting plate 200 and a gripping handle 250, and the adjusting plate 200 is provided with a first connecting shaft 210 and a second connecting shaft 220 parallel to each other, the first connecting shaft 210 is fixed to the outer periphery of the insulating operating rod 100, and the axis of the first connecting shaft 210 is perpendicular to the axis of the insulating operating rod 100, and the adjusting plate 200 is provided with two symmetrical rotating holes 260, the two ends of the first connecting shaft 210 are located in the rotating holes 260, so that the adjusting plate 200 can swing around the first connecting shaft 210, and the second connecting shaft 220 is fixedly connected to the outer periphery of the sliding rod 150, and the second connecting shaft 2 The axis of 20 is perpendicular to the axis of the slide bar 150, and two symmetrical horizontal slide grooves 230 are provided on the adjustment plate 200. The two ends of the second connecting shaft 220 slide in the slide groove, and the holding handle 250 is fixedly set on one side of the adjustment plate 200, specifically on the end away from the position of the first connecting shaft 210 on the adjustment plate 200. The operator pulls the holding handle 250 to move downward, and the holding handle 250 drives the adjustment plate 200 to swing downward with the first connecting shaft 210 as the rotation center, so that the second connecting shaft 220 on the adjustment plate 200 drives the slide bar 150 to move downward relative to the insulating operating rod 100 to separate the terminal post 160 from the top inner wall of the terminal head 110, so as to facilitate clamping the cable to be inspected.

[0049] In order to facilitate the second connecting shaft 220 to slide in the vertical direction, vertical sliding grooves 240 extending along the axial direction are symmetrically opened on the side walls of the insulating operating rod 100. The two ends of the second connecting shaft 220 pass through the vertical sliding grooves 240 and are slidably connected in the horizontal sliding grooves 230 of the adjustment plate 200. Therefore, when the adjustment plate 200 swings downward, it can drive the second connecting shaft 220 to move downward, and the second connecting shaft 220 drives the sliding rod 150 to move downward.

[0050] In a further embodiment, a guiding bevel 120 is provided on the inner wall of the top of the connector 110 of the present invention. The surface of the guiding bevel 120 is smooth and can smoothly contact the cable to be repaired. The guiding bevel 120 has a guiding function and reduces the friction of the cable to be repaired when entering the connector 110, thereby facilitating the entry of the cable to be repaired into the connector 110. A limiting groove 130 is also provided on the inner wall of the top of the connector 110. The limiting groove 130 is an arc-shaped depression. The limiting groove 130 is adapted to the cable to be repaired, and the limiting groove 130 is connected to the guiding bevel 120 in an arc transition. This transition connection method allows the cable to be repaired to achieve seamless connection after being guided by the guiding bevel 120, and naturally and smoothly enter the interior of the limiting groove 130.

[0051] During actual operation, the operator needs to pull the holding handle 250 to separate the terminal post 160 from the top inner wall of the terminal head 110 to make room for the entry of the cable to be inspected, so that the cable to be inspected passes through the guide slope 120 and enters the limiting groove 130. After that, after the operator releases the holding handle 250, the terminal post 160 moves upward under the action of the elastic member 170 to press the cable to be inspected into the limiting groove 130, ensuring that the position of the cable in the terminal head 110 is stable and reliable, and will not be displaced due to slight disturbances of external forces, thereby laying a solid foundation for a series of subsequent operations involving cable connection, detection, etc., and effectively ensuring the efficiency and stability of the entire operation process.

[0052] In a further embodiment, a hinged pile 140 is provided on the outside of the terminal head 110 of this embodiment, and the hinged pile 140 is used to connect the grounding cable 400. A hinged joint 410 is provided on one end of the grounding cable 400. The hinged joint 410 is hinged to the hinged pile 140 on the terminal head 110, and the materials of the hinged joint 410 and the terminal head 110 are both conductive materials, such as copper, aluminum and other materials, which facilitates the connection of the grounding cable 400 to the cable to be inspected.

[0053] It can be understood that the hinged joint 410 of the grounding cable 400 is connected to the hinged pile 140 on the terminal head 110 in a hinged manner. This hinged manner not only ensures the flexibility of the connection, so that the grounding cable 400 can be easily and firmly connected to the terminal head 110 in different working environments and installation angles, but also can buffer the impact of factors such as external force pulling to a certain extent, and effectively prevent the connection from loosening or damage.

[0054] Specifically, in this embodiment, the wire hanging hook 310 at one end of the auxiliary rod 300 is duck-bill-shaped. The duck-bill-shaped wire hanging hook 310 is convenient for hanging on the cable to be inspected. The duck-bill-shaped opening part has a certain curvature and angle. In actual operation, when the staff needs to hang the auxiliary rod 300 on the cable to be inspected, its wide and outward-expanding duck-bill opening can easily align with the cable. Compared with traditional straight hooks or other shapes of wire hanging structures, the duck-bill-shaped wire hanging hook 310 can achieve positioning more quickly, reducing the tedious operation of repeatedly adjusting the position.

[0055] It should be noted that some anti-slip grooves or special rubber pads can be usually set on the inner side of the duckbill-shaped hanging hook 310. Once the hanging hook 310 is successfully hung on the cable to be inspected, these anti-slip measures can effectively increase the friction between the hanging hook 310 and the cable surface, ensuring that in various complex environments, such as when encountering a breeze causing the cable to shake slightly, or when there is a slight vibration caused by the tool touching the cable during the inspection process, the hanging hook 310 can still be firmly fixed on the cable and will not slip easily, thereby providing a stable and reliable support foundation for various subsequent inspection operations carried out with the help of the auxiliary rod 300.

[0056] In a further embodiment, in order to further improve the stability of the connection of the grounding cable 400, as shown in FIG. Figure 6 As shown, a connecting hook 180 is provided on the end of the insulating operating rod 100 away from the terminal 110. The connecting hook 180 is also open. When the grounding cable 400 is connected, the open connecting hook 180 can easily receive the cable, making the cable insertion and connection process smoother and reducing the operational inconvenience that may be caused by the structural limitations of the connecting hook 180. In addition, a fixing clamp 190 is provided in the middle of the outer periphery of the insulating operating rod 100. The fixing clamp 190 and the connecting hook 180 are on the same vertical line. After the grounding cable 400 is hinged to the terminal 110 at one end, it will pass through the fixing clamp 190 along a specific path. The fixing clamp 190 firmly fixes the grounding cable 400 to the outer periphery of the insulating operating rod 100, effectively preventing the grounding cable 400 from moving or shaking during the connection process.

[0057] The grounding cable 400 then continues to extend, passing through the connecting hook 180 and connecting to the grounding assembly (not shown). The coordinated arrangement of the fixing clamp 190 and the connecting hook 180 forms a stable and reliable grounding cable 400 connection system. The fixing clamp 190 constrains the grounding cable 400 from its center, ensuring its stability within the central region of the insulating operating rod 100. The connecting hook 180, on the other hand, provides the final positioning and connection guidance for the grounding cable 400 at one end of the insulating operating rod 100, ensuring a tighter and more stable connection between the grounding cable 400 and the terminal block 110. This dual-security design greatly enhances the reliability of the entire grounding cable 400 connection, effectively reducing potential safety hazards caused by a loose or unstable grounding cable 400 connection, and providing a solid and reliable foundation for subsequent electrical operations.

[0058] Specifically, in order to facilitate the rotation of the insulating operating rod 100 around the auxiliary rod 300, a rectangular through groove 340 is provided on the auxiliary rod 300 in an embodiment of the present invention. The size of the rectangular through groove 340 is adapted to the size of the insulating operating rod 100, that is, the insulating operating rod 100 can pass through the rectangular through groove 340, and the rectangular through groove 340 is connected to the through hole 330, thereby preventing the auxiliary rod 300 from affecting the rotation of the insulating operating rod 100 around the hinge position.

[0059] It can be understood that the insulating operating rod 100 can move just right in the rectangular through groove 340. The insulating operating rod 100 will not shake in it because the rectangular through groove 340 is too large, affecting the stability and accuracy of the operation, nor will the insulating operating rod 100 be difficult to pass through because the rectangular through groove 340 is too small, causing inconvenience in operation.

[0060] The specific use process of the easy-to-operate short-circuit grounding wire device provided by the present invention is described in combination with the above embodiments:

[0061] First, hang the duckbill-shaped hanging hook 310 of the auxiliary rod 300 on the cable to be repaired, then hinge one end of the grounding cable 400 on the terminal head 110 of the insulating operating rod 100, and pass the grounding cable 400 through the fixing clamp 190. The fixing clamp 190 fixes this part of the grounding cable 400 on the insulating operating rod 100, and then hang the hinge shaft 350 in the middle of the entire insulating operating rod 100 in the rotating groove 320 at the bottom end of the auxiliary rod 300. At this time, the terminal head 110 of the insulating operating rod 100 is located at the bottom, and the specific state is shown in Figure 7.

[0062] like Figure 8As shown, the grounding cable 400 is passed through the connecting hook 180 on the insulating operating rod 100. The weight of the grounding cable 400 hanging in the air is greater than the weight of the terminal 110 of the insulating operating rod 100. Therefore, the insulating operating rod 100 is rotated 180 degrees around the rotating groove 320 to form Figure 1 When the operator releases the grip 250, the terminal post 160 moves upward under the action of the resetting of the elastic member 170 to press the cable to be repaired into the limiting groove 130, thereby completing the grounding operation of the cable to be repaired, and subsequent maintenance operations can be performed.

[0063] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
